Lifesource XL-18 pedometer for measuring steps under controlled and free-living conditions     

Sam Liu  Dina Brooks  Scott Thomas  Gunther Eysenbach  Robert Peter Nolan 《Journal of sports sciences》2015,33(10):1001-1006

The primary aim was to examine the criterion and construct validity and test–retest reliability of the Lifesource XL-18 pedometer (A&D Medical, Toronto, ON, Canada) for measuring steps under controlled and free-living activities. The influence of body mass index, waist size and walking speed on the criterion validity of XL-18 was also explored. Forty adults (35–74 years) performed a 6-min walk test in the controlled condition, and the criterion validity of XL-18 was assessed by comparing it to steps counted manually. Thirty-five adults participated in the free-living condition and the construct validity of XL-18 was assessed by comparing it to Yamax SW-200 (YAMAX Health & Sports, Inc., San Antonio, TX, USA). During the controlled condition, XL-18 did not significantly differ from criterion (P > 0.05) and no systematic error was found using Bland–Altman analysis. The accuracy of XL-18 decreased with slower walking speed (P = 0.001). During the free-living condition, Bland–Altman analysis revealed that XL-18 overestimated daily steps by 327 ± 118 than Yamax (P = 0.004). However, the absolute percent error (APE) (6.5 ± 0.58%) was still within an acceptable range. XL-18 did not differ statistically between pant pockets. XL-18 is suitable for measuring steps in controlled and free-living conditions. However, caution may be required when interpreting the steps recorded under slower speeds and free-living conditions.  相似文献   

Research characteristics on health law in China: Social network analysis     

Qing Chang  Chao Long  Mark A. Hall  Zhiguang Duan 《The Journal of Academic Librarianship》2019,45(2):126-136

To determine the nature and extent of the emerging field of “health law” scholarship in China, we retrieved 2956 publications about various aspects of health law published up through 2014 in 268 journals from the “Chinese Social Science Citation Index” and from the list of Chinese “Core Journals” maintained by the Peking University Library. By bibliometric analysis, we observed some interesting results which were different from our expectations. The collaboration network among Chinese health law (CHL) authors was relatively small, loose, unstable and early in its development. Kan Tian and Lixin Yang were leading authors, Renmin University of China was the primary institution, and Beijing was the predominant region studying Chinese health law (CHL). Kan Tian ranked 1st in the collaboration network and Lixin Yang published the most number of articles on CHL. Comprehensive universities made up the majority of institutions studying CHL, while medical colleges did not focus on health law research, possibly due to medical schools focusing mainly on clinical education and not attaching as much importance to social and humanistic aspects of medicine. Food safety, health administration, and the general principles of civil law were the main areas of focus in CHL research, which is basically in line with what we expected.  相似文献

International students with dependent children: the reproduction of gender norms     

Rachel Brooks 《British Journal of Sociology of Education》2015,36(2):195-214

Extant research on family migration for education has focused almost exclusively on the education of children. We thus know very little about family migration when it is driven by the educational projects of parents. To begin to redress this gap, this paper explores the experiences of families who have moved to the United Kingdom primarily to enable the mother or father to pursue a degree. It argues that, in common with what we know of UK student-parents, both choices about and experiences of higher education are strongly differentiated by gender.  相似文献   

Effects of learner–instructor relationship-building strategies in online video instruction     

Yanghee Kim  Jeffrey Thayne 《Distance Education》2015,36(1):100-114

Although research has demonstrated that an increased rapport between instructors and learners can positively relate with increased learning gains, perhaps mediated by the positive attitudes toward the course and self-efficacy beliefs in the coursework, little has been done to test what instructional strategies might increase this rapport in online video-based instruction. This study compared online video-based instruction that made use of relationship-building strategies with online video-based instruction that did not use those strategies. The two instructions were identical in every other way. The results show that the attitudes of the college students were positively affected by the relationship building strategies in a statistically significant way (p = .025) and that learning gains were also positively affected at a very near-significant level (p = .052). The implications of the findings are discussed.  相似文献

Ten Salient Practices of Undergraduate Research Mentors: A Review of the Literature     

Jenny Olin Shanahan  Elizabeth Ackley-Holbrook  Eric Hall  Kearsley Stewart  Helen Walkington 《Mentoring & Tutoring: Partnership in Learning》2015,23(5):359-376

This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches.  相似文献
